BOTTLE STOPPER AND FASTENElR.

SPECIFICATION forming part of Letters Patent No. 223,526, dated January 13, 1880.

Application filed April :25, 1879.

To all whom it may concern Be it known that I, ROBERT McOULLY, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bottle- Stoppers; and I do hereby declare the followin g to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in Which-- Figures and 6 are transverse vertical sections of a bottle-neck having my improvements applied thereto. Figs. 2, 3, and 5 are side elevarious of the same. Fig. 4 is a perspective of my invention, and Fig. 7 is a detail section of the stopper and valve.

My invention has for its object to provide a stopple adapted to fit the neck of an ordinary mineral-water or similar bottle, and so constructed that pressure of liquids or gas within the bottle will have the eii ect of ti ghtenin g said stopple in position.

My invention consists in the peculiar construction of the stopple hereinafter set forth, having reference principally to the provision,. in a metallic stopple having an india-rubber gasket and held in place in a bottle by a wire plied.

Referring to the accompanying drawings, A indicates a metallic stopper composed of a disk, a, with cylindrical neck a and annular flange a B represents a plug having a tapering end, I), and cylindrical shank b, which latter passes through the neck a and projects up into the flange a Said plug-shank b is slotted laterally at b and the flange a is notched or cut away at a a for the passage of a wire bail, G. The depending ends 0 c of said bail are turned inwardly to enter openings (1 (1, formed in toggle-links D D. Said toggles consist of metallic plates or castings having the lugs 01 d and trunnions 61 M, which latter enter eyes 0 c in a wire collar, E, secured to the neck F of a bottle, or in similar openings g g in a semicircular band, Gr, held on said neck by said collar E. It said band G be employed, it is formed with stops 9 g, which limit the movement of'the links 1) D, and prevent the fog gles from passing too far from their centers. It the collar E alone be employed, (the collarband Gr being omitted,) the links D D will be formed with studs d (1*, which, when the toggles reach a verticalposition, come in contact with said collar E, shown in Fig. 4, and

the neck a and affording aseat for the conical or tapering portion 11 of the plug B.

The operation is as follows: The parts being connected as shown and described, the stopple,

- being inserted in the neck of the bottle, is fastened therein by turning down the toggle-links D D until they assume a verticalposition, as shown in Figs. 1 and 2. The stopper proper cannot now be drawn out of the bottle-neck until said links are thrown back; but any sufiicient fluid or gaseous pressure exerted inside the bottle will force the plug B upwardly or outwardly, compressing the gasket H vertically and expanding it laterally, tightening the joint formed thereby, the slot 1) in the shank of said plug permitting the movement of the latter, while the stopple proper and bail remain undisturbed.

What 1 claim as my invention is- 1. The combination,with gasket H and tapering plug B, having shank b, with slot b of disk a, having neck a, with slot a and bail 0, passing through said slots, substantially as' described.

2. The combination, with stopple A, having plug B, with slotted shank, the slot thereof being longer than the diameter of the bail-Wire, of bail (J, passing through said plug, whereby the latter is adapted to be moved upwardly or outward y to expand the gasket and tighten the joint While said bail and stopple remain stationary, as set forth.

3. The combination, with a stopple, A, and hail O, of toggle D D, constructed and adapted to receive the depending ends of said bail, and a collar, E, or band G and collar E, substantially as shown and set forth.

April, 1879.

ROBERT MCOULLY.
